PRODUCE

DYNAMITE COLOR-Byw GRAPHICS

By Norm Lehfeldt

High-resolution black-and-white or color screen duaps for both the Timex/Sinclair 2048/Spectrua and the Sinclair @L are implemented with two new software packages.

For the GL, Don Thoapson of Martinez, CA has produced a monochrome duap utility for the Olivetti PR 2300, ink-jet printer and a full-color duap for the color ink-jet printer built by Canon and marketed also with Radio Shack and IBM nage plates.

The sonochrome utility reproduces the colors from the OL

screen aS a series of different stipples so that there is pleasing contrast between adjacent areas of different colors. The color duap reproduces the colors on the QL screen with remarkable accuracy, given the differences between color phosophors and color inks.

Both of Don’s progrags reproduce the screen either as a one-page, full-size horizontal dump or in ’zoom’ aode which magnifies any selected portion of the screen by two diameters. Using this feature it is possible to copy the whole screen on two strips of paper which can then be taped together for a poster-sized print-out! Both prograas offer positive or negative image print-outs. In the color prograa only black and white are swapped in the negative aade. This feature is especially useful in printing ’Ease’ graphs, since you don’t waste a lot of ink reproducing the black of the sonitor screen. Both utilities also feature well-thought-out SuperBASIC loader prograas which let you select the various options fros attractively designed aenu screens.

Don’s programs are marketed by Curry Computer.

For the 2068, Dave Franson has created and is marketing a set

_Of color screen duaps that reproduce that coaputer’s color

displays on the same Canon-Radio Shack-1BM color ink-jet printer.

The fully-relocatable sachine-code routines (and their BASIC

loading-relocating programs) are provided on opposite sides of a single cassette and produce either a? i/4" YX 3" or a 4.5" ¥ 6" color screen dump. It should be possible to load both drivers at once and switch back and forth between isage sizes by appropriate USR calts. (I believe it is also possible to load them along with Jack Dohaney’s relocatable AERCO I/F driver and thus have your program switch easily between text and graphics printing.)

Supplying the two drivers separately greatly enhances the flexibility you will have in incorporating them into your own prograas. Only the AERCO printer interface is supported by the drivers.

FROM SEPT. 15-28 YTUICE NSL.

Amstrad To Bow New IBM Compatibles From $595

sonal computer market on its ear, Am- strad, the maverick British consumer electronics marketer, has announced plans for the introduction and international sale of an eight-model line of low priced IBM- compaubles. The new models range from a leader

frat to set the $34 billion world per-

designed to list in England at about $595.

to a high-end business oriented version with color monitor and hard disc drive at under $1,500. Alan Sugar, Amstrad's chairman, says the machines are already being turned out in the Far East on a pro- duction schedule that calls for a rate of 70,000 monthly, and that he is looking for sales in Europe of 300,000 total units by the end of this year.

A sales start in the US. is scheduled for early next year, and Sugar says he should be able to move 50,000 to 60,000 a month here. Production in 1987, he claims, will then jump to 100,000 month- ly, and worldwide sales for the year should hit at least 800,000. If Amstrad

even comes close to its volume goals, it could put a severe competitive crimp in the marketing plans of the U.S. low end computer leaders Atari and Commodore, while siphoning off a major chunk of busi- ness from a host of smaller computer com- panies marketing low-end IBM clones. Relatively unknown here, Amstrad has through sharp pricing and marketing tac- tics established itself as a major video and audio equipment company in the U.K., and one of the biggest players in the Eu- rope-wide computer market, with a 34 percent share. Last spring it acquired Sin- clair’s computer business, along with con- sumer electronics brand rights, for $7.5 million. Just now finding its way into stores here is Amstrad’s Korean-made packaged $799 personal word processing system that includes a computer, disc drive, software, monitor and printer. It's being distributed under an exclusive agreement by Sears World Trade Corp. Whether Sears will also handle Amstrad’s new IBM compatible PCs is uncertain.

BETTER RGB CIRCUIT by Joe Williamson

FROM THE JULY 1996 SUH NY/L.

LETTERS Electronics / August 7, 1986

Sinclair is still kicking To the editor: Your issue of June 23 con- tains a serious error. It is not true that Amstrad Consumer Electronics ple bought Sinclair Research Ltd. [Elec- tronics, June 23, 1986 p. 53]. They sim- ply bought the existing computer range and the right to the use of the brand name. They have no right to any future computer products or any other product categories. A portable computer is un- der development, but by my team and for my company. We plan to launch it in

the first half of 1987.

Str Clive Sinclair Chairman Sinclair Research Ltd. London

The circuit described in the february 1986 issue of SUM was designed around the

Sears RGB/TV/Monitor (same as the Sanyo model # 31C426) and the Magnavox (NAP) r r‘ RGB-40 or 80. Pn ae Composite of QY | 100 PF Syne Both of these monitors (and the QL in 2068 Out monitor as well) take negative-going eek

composite sync and active high RGB signals and have well buffered inputs to clean up any poor inputs.

Many RGB monitors out on the market don't have these features and therefore do not work very well or at all with the

circuit described. With the simple addition of a 74LS86 Quad 2-input Exclusive OR gate, you can shape (buffer)

and invert all four signals to what ever format you need by changing the polarity of one of the two input lines on each of the four gates.

Also, I neglected to say what transistor was used in the original circuit; it is a 2N2222, Radio Shack #276- 2009. Although, any garden variety NPN transistor should work.

deals with the trans-

MTrERM Srure By Bill Strick

Now that there is a sizeable oroup of RODEN Owners. perhaos

a little advice concerning the use of these sarvels will pro- mote a sharpening of interest in their use and an increase in the exchange of useful information between al! of us. Follow- ing are some hints regarding data transmission via MODEN,

A. TO TRANSMIT (XMIT) SENDER aoes to BUFFER MEMU and erases Butter contents. Back to HAIN MENU, EXITS to BASIC and LOADS or MERGES data to be

transmitted. (See Section C for details.)

Phone the person to receive the above data and determine (via voice) that the parameter settings agree as shows below:

SENDER RECEIVER BOTH BUF: CLOSED BUF: CLOSED (Opened by MIT: OFF DUP: HALF DUP: FULL = XNIT OP) = -voRD: 7 LF: ON LF: OFF STOP: 3 CR: OFF CR: OFF PRTY: EVEN

CON: NONE (text) ‘(HEX for other)

CON: NONE (text) DSP¥: 32 > (HEX for other}

SENDER informs RECEIVER to {!) clear bufter. {2) qo to terminal mode. and (3) connect uo via MODEM COMNAND ¥,

To access MODEN COMMANDS. press CAPS SHIFT & ENTER together. ENTER M to connect. SENDER also CONNECTS as described. Both users leave phone receiver off hook. CONNECT will take place with a displayed signal and sound,

From this ooint. ANY activity is in the hands of SENDER ONLY!

After CONNECT signal, SENDER opens the RECEIVER’s butter by executing a CONTROL R {CAPS SHIFT & 7 and then eaters an R).

SENDER sow returns to NAIN/MENU using CAPS SHIFT 8 and calls up BUFFER MENU. ENTERS T to transmit text in buffer.

ENTER four tines: #1 after prompt- *Prosot Strisq’ #2 after proaot- "Character delay’ #3 returns SENDER to HAIN NENU #4 enters TERMINAL MODE

This begins transmisson which can be viewed on screen.

After end of transmission. SENDER closes RECEIVER’s butter with a CONTROL T (CAPS SHIFT & 7. then 1).

SENDER then enters BELL signal (CONTROL G...CAPS SHIFT & 7, then 6). which signals the end of transmission {XMIT) to RECEIVER.

Atter BELL, both USERS disconnect by doing a MODEM COMMAND H (CAPS SHIFT & ENTER . then H) to “Hang up” modems. They can how converse freely on their telenhones.

NOTE: If “Waiting Caller" service is on SENDER’s phone, it will be necessary (before using MODEM) to cancel this service temporarily. This can be done by dialling STAR ("8") 70 for a touchtone shone or 1170 for a oulsetone phone.

B. TO MOVE NTERN BUFFER CONTENTS TO MSCRIPT

To save eaterial from Moder buffer. first note the length of Butter used (BUFUSD). Then EXIT to BASIC and SAVE.

To Tape: SAVE "(name)" CODE 26710. (length) To AERCO BDS: MOVE (drivel: (name) .bin’. 26710, (length) To ZEBRA DBS: SAVE #"(name)” CODE 26710. (length)

LOAD MSCRIPT. LOAD saved materia] from Home Henu.

C. TO TRANSMIT MSCRIPT FILES OR BIN.COD VIA NTERN First. move file to MTERM buffer as outlined below:

¥ Make a note of document (file) Jenath {trom a DIRECTORY or CATALOG listing or from a Header Reading).

% SAVE document to tape or disk.

% LOAD NTERH. Go to Buffer Menu.

% Clear buffer. EXIT to BASIC.

% Open up program area with DIN AS (document length).

Since this expands VARS (not the orogras area): POKE 23627, PEEK 23641: POKE 23628, PEEK 23442 Now LOAD = from Tane: LOA "* CODE 26710 from AERCO BPS: CAT "(érive): (name). bin’. 26710 from ZEBRA DBS: LOAD & "(nase)" CODE 26710

The command. PRINT USR 54016. will restore MTERM with document fully installed in its Buffer and ready for transmission.

NOTE: Some BBS systems require LF after each line. so you may have to add them before leaving NSCRIPT.

IMELINE Greetings Fellow Sinclair Users, | 260 |

We are two people who still get a great deal of Satisfaction out of our humble computers. We've spent many, | many hours telecommunicating all over the U.S. to every w BBS that we could find which supports our machines. We did 7 not want all this effort and time to be wasted on our own uses alone. So we got together and wrote a small publication called,"The T/S Guide to telecommunication".

This is an entirely FREE publication, no copyrights will apply. We enclose an outline of the document in pro- gress. We intend to send you a copy when it is ready. In the mean time, we wanted you to have the information on the enclosed chart which gives the names, numbers,hours and settings of all the boards that we could find. We would hope that you could see fit to publish this in your User Group Newsletter. Failing that we would hope you might make it available to all your members by xeroxing at the User Group meeting. As I said, we spent many,hours on the phone verifying all this information, and are prepared to say that it's accurate (until it changes). The guide has a much more detailed description of each of these boards, as well as descriptions of all the modems, terminal programs and hardware add-ons that we could find. It should certainly be in your hands by the end of October.

Take it easy, and keep on TIMEXing!

This program will display a pie chart and the values for each of up to 18 pieces of the pie. If sore than 18 pieces of the pie are entered then the %‘s coluan will not line up with the values entered due to scrolling. The PLOTing routine is placed at the beginning of the program for speed. Depending on the pie slice densities, typical PLOTing time can run between 2 and 15 minutes.

EBZUG NEws BY FRED TEMPLETON

REPORT ON MEETING QF NOVEMBER 28th.

Meeting was called to order shortly after 8:@0PM by Joeseph Randall. The meeting was started by everybody identifing themselves and there current interests and/or projects. Reqular members in attendence were Ivor Alma, Russell English, John Ezike, Tom Fattaruso, Fred James, Alvin Lam, Woody McPheeters, Bill Miller, Joseph Randall, Wayne Seibel, Fred Templeton, Darwin Thompson, and Kevin Zimmerman. In addition Erwin Mead from GUTS visisted us, and we welcomed two new members MATT MOORE and DANIEL L. MOORE (not related)

Darwin Thompson informed us that the GL has been selling for as low as 199.808 at At Computer Response 69-B Island St. Keene, NH O3431 (46803) 357-1808. He reported that they can help with almost any added option to configure a system to anyones needs. It is unknow if Sunset Electronics is matching the price. It seems the price decline is due to an upcomming change in the QL‘s distribution network.

Russell English brought to our attention that most parts for the 2048 are available at most electronics stores except the SCLD chip which is custom to the 2048. There is a souce and he reported that the group could join the other user groups ts purchase some. A vote was taken to purchase one for our general inventory, which did not pass. t was suggested that those who are interested put up the cash and share the risk. Price 1-$25.08 3 or more $18.88.

One of the main events of the night's meeting was a video of the TIMEX/SINCLAIR Computer Fest in Cincinatti, Ohio this May ; The video was as exciting as watching the opening of Al Capone's undergound vault--empty. The entire 15 minute feature was a constant Par ny view of the people there without a stad e feature or interview. At least we did get to see some of the exhibitors displays. Although the video was limited it did show that there were plenty of people there.

I got a chance to show off my 2848 word-processor with multi-tasking abilities but I blew it when I POKED the wrong address into the vector table and caused the printer output to get scrambled and ultimately to crash the whole system. Fortunately I printed out the beginning of this article on the 2048 printer (while the EPSON printer was printing something else) before the crash.

ThiS routine will never cause a Printer to tock up. The time taken by the 20658 to process a keyboard interrupt is often more than 158 microseconds. If this interrupt was permitted whi le STB Was iow, the ACK $ignal could arrive from the Pranter before STB went high again,

In this routine, interrupts are blocked white the STB pulse 15 being sent.

For those not familiar with STB and ACK, the STB is a Signal tO the printer that valid data is present on the data wires. The RACK 35 an acknowledgement signal from the Printer that the data has been received, and cirer things are normal,

Both $ignals are puises heving the timing stowh ain Figure 1.

The ACK pulse Can be as Short as & microseconds. 2068 code (OOP LO test if it is there tates longer than thet. Part of the time the Signal will be missed. That is why the BUSY signal is tested instead. The reason for the ACK signat is to generate an interrupt when that operating mode is in USe. The ZEB PIO can be configured that wey but the 2068 does not operate ins IH2 as a generat cule, (Vectoréed interrupt mode)

When things are not normal, tike funning out of paper, or the Printer cover is open; the program heees locrina. In order to bf@ak out of this Loop, use is made of the ROM Subroutine BREAK? at sddréss 8281. Usually, this is SUFfACiEnt because printers indicate when they are at FRULT with an alarm andsor light. If not, you Might wart 10 test the printer status after calling the BREAK? routine. This is tine Gilding # lily, though,
